Experimental setup for an empirical study on the experience of brightness/darkness in musical harmony perception, so-called "harmonic luminosity." The study was part of Ville Langfeldt's PhD project Gestalt listening: A theoretical and empirical study on holistic harmony perception (Norwegian Academy of Music, 2022).

This task consists of 16 three-chord stimuli in ABA pattern. In these stimuli, the A chords are intended to act as a tonally “neutral” element, while the middle B chord is a contrast chord. The hypothesis predicted the B chord in each stimulus to be perceived as either "brightening" or "darkening." Participants play back the audio clip, and are asked to choose between four reply options: A dark cloud representing "darker," a bright sun representing "brighter," "Sounds about the same," or "I don't know."
All stimuli were made using Cubase 10.5 software with a naturalistic piano plugin (Alicia’s Keys) using equal temperament. All chords were performed as whole notes at 120 bpm. Stimuli lasted 6.22 seconds. Note onsets and velocity were uniform for all chord tones and across all stimuli.

This task consists of 19 three- or five-chord stimuli in ABC pattern. It measures whether clockwise movement along the circle of fifths corresponds with a sense of harmonic "brightening," while counterclockwise movement corresponds with a sense of harmonic "darkening." Participants play back an audio clip consisting of three or five chords. They are then asked to chose one of four reply options: A dark cloud representing "darker," a bright sun representing "brighter," "Vague / No clear change either way," or "I don't know."
All stimuli were made using Cubase 10.5 software with a naturalistic piano plugin (Alicia’s Keys) using equal temperament. All chords were performed as whole notes at 120 bpm. All three-chord stimuli (33 of 35) lasted 6.22 seconds, while five-chord stimuli (2 of 35) lasted 10.17 seconds. Note onsets and velocity were uniform for all chord tones and across all stimuli.
